Auxin-dependent cell cycle reactivation through transcriptional regulation of Arabidopsis E2Fa by lateral organ boundary proteins [PDF]

open access: yes, 2011
Multicellular organisms depend on cell production, cell fate specification, and correct patterning to shape their adult body. In plants, auxin plays a prominent role in the timely coordination of these different cellular processes. A well-studied example

Auxin Is Surfacing [PDF]

open access: yesACS Chemical Biology, 2007
Indole-3-acetic acid (IAA or auxin) is essential throughout the life cycle of a plant. It controls diverse cellular processes, including gene expression. The hormone is perceived by a ubiquitin protein ligase (E3) and triggers the rapid destruction of repressors, called Aux/IAA proteins.

Auxin signal transduction into a quantitative change in natural auxin polar transport in pine cambium

open access: yesActa Societatis Botanicorum Poloniae, 2014
Results of experiments performed with 6-mm high stem sections of Pinus sylvestris L. confirmed the hypothesis that the fusiform cells of the cambial region respond to the arrival of indole-3-acetic-acid (IAA) at the signalling concentration in the ...

Cell Dynamics in WOX5-Overexpressing Root Tips: The Impact of Local Auxin Biosynthesis

open access: yesFrontiers in Plant Science, 2020
Root stem cell niche functioning requires the formation and maintenance of the specific “auxin-rich domain” governed by directional auxin transport and local auxin production.

Local auxin synthesis mediated by YUCCA4 induced during root-knot nematode infection positively regulates gall growth and nematode development

open access: yesFrontiers in Plant Science, 2022
Parasites and pathogens are known to manipulate the host’s endogenous signaling pathways to facilitate the infection process. In particular, plant-parasitic root-knot nematodes (RKN) are known to elicit auxin response at the infection sites, to aid the ...

The IBR5 phosphatase promotes Arabidopsis auxin responses through a novel mechanism distinct from TIR1-mediated repressor degradation

open access: yesBMC Plant Biology, 2008
Background In Arabidopsis, INDOLE-3-BUTYRIC ACID RESPONSE5 (IBR5), a putative dual-specificity protein phosphatase, is a positive regulator of auxin response.

The transcription factors BEL1 and SPL are required for cytokinin and auxin signaling during ovule development in Arabidopsis [PDF]

open access: yes, 2012
Hormones, such as auxin and cytokinin, are involved in the complex molecular network that regulates the coordinated development of plant organs. Genes controlling ovule patterning have been identified and studied in detail; however, the roles of auxin ...

A Photonastic Prototissue Capable of Photo‐Mechano‐Chemical Transduction

open access: yesAdvanced Materials, EarlyView.
Mimicking energy transduction in prototissue assemblies remains a challenge of bottom‐up synthetic biology. In this work, prototissues integrating protocells with photothermal gold nanoparticle proto‐organelles and a thermoresponsive polymeric proto‐cortex are developed.

Auxin influx carriers control vascular patterning and xylem differentiation in Arabidopsis thaliana.

open access: yesPLoS Genetics, 2015
Auxin is an essential hormone for plant growth and development. Auxin influx carriers AUX1/LAX transport auxin into the cell, while auxin efflux carriers PIN pump it out of the cell.

The AUXIN BINDING PROTEIN 1 is required for differential auxin responses mediating root growth.

open access: yesPLoS ONE, 2009
BackgroundIn plants, the phytohormone auxin is a crucial regulator sustaining growth and development. At the cellular level, auxin is interpreted differentially in a tissue- and dose-dependent manner.
